Parts for Mtd 265-SU-11: Su-11 Crankcase Parts

Piston ring set seals the combustion chamber in lawn mower, snow thrower, and tiller engines. Replace when compression drops or oil consumption increases. Verify fit with your model number.

Metal connecting rod assembly that links the crankshaft to the piston in small engines. Replace if rod is bent, cracked, or damaged from wear or impact.

Governor arm shaft for small engines on lawn and garden equipment. Connects governor assembly to carburetor. Replace if worn, damaged, or broken.

Engine won't start or runs rough? This camshaft assembly converts rotational motion to reciprocal motion for proper engine operation. Moderate DIY repair.

Engine won't start after sudden stop? A sheared flywheel key breaks the connection between crankshaft and flywheel. Simple DIY repair.

Engine surging or racing? Replace a worn governor gear and shaft assembly. Critical for speed control on small engines. Moderate DIY repair.

This is a crankcase gasket that seals the crankcase cover to the engine block on a lawn mower. It prevents oil from leaking out of the engine and keeps contaminants from entering the crankcase. Replace this gasket if you notice oil pooling beneath the engine, visible oil seepage around the crankcase cover, or if the gasket is torn or deteriorated.

Oil fill plug assembly for small engines. Seals the oil fill opening to prevent leaks. Replace if cracked, stripped, or missing to maintain proper seal.

This oil seal fits around a rotating shaft in a small engine, preventing oil from leaking out of the crankcase or transmission housing. It creates a tight barrier between moving and stationary engine components to maintain proper lubrication. Replace this seal if you notice oil dripping or pooling beneath your equipment, or if the engine is losing oil without an obvious external leak.

Oil drain pipe for small engines and snow throwers. Replaces cracked, broken, or corroded drain pipes. Installs on engine block for oil changes.

Replacement oil drain plug for outdoor power equipment engines. Installs in the oil pan to seal the drain opening. Replace if stripped, cracked, or leaking.

Engine oil seal prevents oil leaks in snow thrower engines. Replace if you notice oil seeping around the crankshaft or engine case. Verify fit with your model.

Replace a leaking or damaged oil drain assembly on your snowblower engine. Includes valve for easier oil changes. Basic hand tools required.

This is a short block assembly for a small engine, consisting of the engine block, crankshaft, piston, and connecting rod as a pre-assembled unit. It serves as the core mechanical foundation of the engine, providing the compression and power generation needed to operate the equipment. Replace this assembly if the engine has seized, has low or no compression, or shows signs of significant internal damage such as scoring on the cylinder walls.

External gasket kit seals carburetor and engine surfaces on lawn equipment. Replace when you notice fuel leaks or loss of compression. Verify fit with your model.

This complete gasket kit includes the gaskets needed to seal various engine components on outdoor power equipment. The gaskets prevent oil, fuel, and air leaks between mating surfaces such as the cylinder head, crankcase, and carburetor. Replace if you notice oil or fuel leaks, loss of engine compression, rough running, or if gaskets appear cracked, brittle, or damaged during an engine rebuild.
